RemoteBox warns of out of date or not installed extpack, but I am current 5.1.28
A client for the remote use of VirtualBox on a server

Trying to get a headless Ubuntu 16.04 server to run my VM's...I have Win XP and Ubuntu 12.04 VM's among others. Every time I connect RemoteBox to my headless server it gripes about the extpack, even though I have the correct one installed. I am unable to get remote desktop view to work at all. Any direction?

My guess is that the extension pack isn't being "seen" by the user that the vboxweb service is running as. I'm also assuming that if the extension pack is installed, it's been installed as root and vboxwebsrv is perhaps running as different user? Try su-ing or logging in as that user on the server and running:
vboxmanage extpack install --replace theextensionpackfile
Even if it produces errors, it should force VirtualBox to see any system-wide installed extension pack. RemoteBox may be griping, but it seems correctly so. RDP (remote desktop view) is part of the extension pack so if that isn't working, the extension pack is not installed or incorrectly installed.
It won't install as anything but root. I tried the "current" setup here and I also tried backing up to 5.0 and it still causes the issues. Also I seem to have trouble getting "vboxweb-service" to run. There is a thing called vboxwebsrv running though. Did they change the name of it? Nothing seems to be working now.
It would appear that the switch from Upstart to Systemd has tripped me up. I will revert to 14.04 server for now, and set about learning more about Systemd before upgrading my server. It is a VM and SSH host mostly, so it really doesn't do network "server" duty at any complex level...yet.
For systemd
systemctl enable vboxdrv.service vboxweb-service.service
systemctl start vboxdrv.service vboxweb-service.service
Should be all you really need to do, provided you've configured the vboxweb-service
